The Fungi Formerly Known as Dentinum Repandum :: Hydnum Repandum Fungus Essays

The Fungi Formerly Known as Dentinum RepandumThis paper will cover a description of Hydnum repandum, its ecology, and some question involving the species.The first topic to be discussed in this paper is a description of Hydnum repandum, which was until recently referred to as Dentinum repandum. The description of the fungi will start with the bearing of H. repandum, and will be followed by the life cycle of the noted species.The appearance of Hydnum repandum is quite unique. The stipe of the fungi can range from two to seven centimeters tall, and whiz to three centimeters thick (Wood). The surface of the stipe can range from cream to yellow in color, and is prohibitionist and smooth. The cap of the mushroom is two to ten centimeters broad, with a smooth, dry surface (Graham 84). The caps color can range from cream to orange. It has a thick flesh that is very brittle, with a mild taste and odor. The hymenophore has teeth that atomic number 18 0.4 to 0.6 centimeters long. They ar e cream colored, and also brittle (Wood).The life cycle of Hydnum repandum is fairly simple, as you can see from Figure 2. It falls into the subdivision of Eumycota, called Basidiomycotina (Ross 18). This concourse contains many large, fleshy fungi, To begin this discussion on the life cycle of Hydnum Repandum, this text will start with the basidiospore germination (Webster 295). This results in a monoploid mycelium with a single nucleus in each cell. It is then referred to as the monokaryon, or the primary mycelium (Ross 141). Following this, two genetically different thalli come together, and the nuclei hold up from one thallus into another. The migration of nuclei usually results in both of the thalli becoming dikaryotic (Ross 142). This nuclear migration is very quick, and every hyphal tip becomes binucleate. The subsequent growth of the mushroom is all dikaryon (Ross 143). The next yard includes the two nuclei of the dikaryon fusing through karyogomy (Ross 146). The resulti ng diploid zygotic nucleus then undergoes meiosis, and four haploid nuclei are formed in the basidium (Webster 280). The haploid nuclei move into projections on the basidium, which consider into spores. The spores are attached to the sterigmata until they are released (Ross 146). The cycle then starts over again.The next topic for discussion in this paper is ecology. This will include, preferred habitats and interactions with abiotic and biotic elements of the environment.

tragoed Oedipus the King (Oedipus Rex) as Greek Tragedy :: Oedipus the King Oedipus Rex

Oedipus The King as Greek Tragedy The genre of drama is wide and contains works of varied forms and subjects. The first drama, on which all later works are based, developed in Greece and circumstancest with religious and social issues. According to Aristotles The Poetics, a Greek Tragedy must deal with a serious purpose, arousing a sense of pity or fear in the hearing. The emphasis must be on plot over pillow slip development and the playwright must utilize suspense and unity of time, place and action. Aristotle writes that a tragic hero is a character who is renowned and prosperous, not needfully perfect, but not an evil person either. The tragic hero must meet with a reversal of fortune brought about by either unwiseness or fate. Based on these criteria, Oedipus the King by Sophocles is considered the prototypical Greek Tragedy. Oedipus, the plays main character, is also considered the model of a Greek tragic hero. Oedipus the King deals with several serious purp oses, the greatest of which being the agnosticism Sophocles perceived in his community. Through Iokaste who would not waste a second thought on oracles, Sophocles shows his audience the perils of disbelief in the gods, since each prophecy made by oracles in the play ended up coming true (l. 813). Sophocles uses his play to practice serious religious functions as well as to entertain theatre-goers. The fulfillment of the predictions made by the oracles led to the downfall of Oedipus, which created a catharsis in the audience, brought by arousing feelings of pity and fear for the fallen king. The Choragos gives the lesson, let none presume on his good fortune until he find life, at his death, a memory without hassle (l. 1473-5). This scene allows the audience to leave the theater feeling purged of their pity and fear. The plot is the most important component of Oedipus the King, as it is of every Greek Tragedy. Development of characters is secondary, and the audience rarely gets inside any of the characters. Only characters crucial to the plot are introduced there is no extraneous action on stage. This development of plot is a challenge. A tragedian must present a story with which the audience is already familiar and still make it interesting

From the 186 societies, only a handful of them fell into the category of the uncertains this paper is centered upon high ext. vs. int. war were the Yanomamo, Comanche, Maori, Jivaro, and Somali. In Rosss article about conflict and violence, a measurement of internal and external violence was done using 44 variables for the 90 societies. The areas of gratify for the table are those measuring internal and external violence. The factor loading is determined by the sum of the scores of each society for each variable and is weighted individually for each society. The six variables in the internal violence and conflict scale, in descending order of importance, are//./ The severity of conflict among different communities of the homogeneous society (v767), the acceptableness of violence when directed against members of the same society outside the local community (v782), frequency of internal warfare (v773), the same severity of conflict within the local community (v764), the extent to which physical force is used as a mechanism for the dispute settlement (v770), the acceptability of violence when directed against members of the local community(v781) and degree of compliance with community norms and decisions by members of local communities(v775). Societies that scored high on this end of the scale, for example Jivaro or Somali, frequently employed in violence and internal warfare both within and between communities of the s ame society. Societies that fell into the middle of the scale engaged in regular conflict, just internal warfare and violence in local disputes occur less frequently than the previous category of societies. The 3 variables that compose the external warfare and conflict scale are frequency of external warfare(v774), degreee of hostility(v780), and the acceptability of violence directed to people in other societies(v783). The Maori, Comanche and Jivaro are societies of the high end of the scale. From the large number of research done on violence and conflict, there exist 3 characteristics of societies that are agreed upon by the majority.
